The 17-year-old Kotoko has a unique situation. When she was a child, she was kidnapped by spirits called yōkai, and returned missing one leg and one eye. Since then, she has been able to communicate with otherworldly forces, both benevolent and dangerous. Kotoko is alone in her power until she learns that the crush she's watched from afar, Kurō, has had his own encounter with yōkai! As if being touched by the supernatural wasn't enough, Kurō's personal life is also in shambles. With their shared experiences and understanding, Kotoko and Kurō form a partnership to deal with mysteries, from ancient demons to the ghost of an idol. But for a girl who's used to dealing with spirits, winning love might prove to be the bigger challenge!
